Specification of Letters Patent.

Patented Apr. 25, I916.

To all whom it may concern:

Be it known that I, CHARLES F. Lnrnvnn, a citizen of the United Statesof America, residing at Plymouth, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in SpringAir-Guns, of which the following is a specification, reference being hadtherein to the accompanying drawings.

The invention relates to spring air guns of the type in which the springis tensioned by a mechanism simulating the so-called pump guns.

It is the object of the present invention to simplify the constructionof the springcompression mechanism, and to this end the inventioncomprises, first, the construction in which the rearward movement of theactuating handle causes the compression of the spring against theplunger abutment, while the forward movement of said handle moves theplunger and compressed spring rearward to the firing position.

The invention also has reference to the construction of sear and triggerlocking mechanism, and further to various details of construction ashereinafter set forth:

In the drawings :Figure 1 is a side elevation of the gun; Fig. 2 is alongitudinal section thereof when the spring is released; Fig. 3 is asimilar view showing the operation of compressing and retracting thespring; Figs. 4:, 5 and 6 are perspective views respectively of thefalse barrel, the frame and the lever mechanism; and Fig. 7 is a sectionsimilar to Figs. 2 and 3 showing the spring compressed and in firingposition. Fig. 8 is a detail cross section taken through the leverhandle. Fig. 9 is a detail perspective view of a locking member or dog.Fig. 10 is a detail perspective view of the trigger.

A is the false barrel of the gun within which the true or firing barrel(not shown) is located.

B is the actuating member or pump handle for the spring compressionmechanism. This is slidably secured to the false barrel by attaching tothe latter a longitudinallyextending strip C having projecting lips Cwhich are embraced by a U-shaped guide member D secured to the handle.This guide member is preferably struck-up from opposite ends whichembrace the wooden handle B.

E is a shank member having a shouldered head E at one end and a bodyportion of reduced diameter which passes through apertures in the ears Dand an alined aperture in the handle B, while its opposite end isprovided with clenched flanges E for re taining it from displacement.

F is the frame member which is struck up from sheet metal to formparallel sides with a rounded top portion F and a flat bottom portion FThe under side of this member is slotted at F to receive the dependingflanges A of the barrel A, which flanges form a fulcrum support andguide for the lever mechanism. The frame member F is further providedwith a trigger guard G, the forward end of which is embraced by theflanges A and secured thereto by a rivet G.

To secure the barrel A to the frame F, the two parts are telescopicallyengaged until apertures F in the member F are registered with aperturesA in the flanges A. A cross pinH is then inserted, which will lock thesetwo parts together, and to prevent any looseness or rattling, therearward end of the barrel is provided with a tapering or wedge shapedportion A which engages a cross pin H at the rear end of the frame.

I is the plunger which slidably engages a portion of the barrel A inrear of the abutment J.

K is a spring for actuating the plunger I, which is sleeved about ashank I of said plunger, having a tapering point I with a shoulder Iadjacent thereto.

L is a movable abutment slidable within the barrel A and operated by thebreakjoint levers M M, which in turn are secured to and operated by thehandle B. The lever M is fulcrumed upon a cross pin N engag ingapertures N in the flanges A. The general form of the lever M is that ofa bell-crank, which is pivotally connected at its free end with thesliding abutment L through the medium of a pivotal link 0. The levers Mand M and the link 0 will preferably be made of sheet metal, bifurcatedin form. The sliding abutment L is hollow, and within the same isarranged the sear P, which is in the form of a lever pivoted upon thepin P which also forms the connection for the link 0. The forward end ofthe lever P has a hook P for engagthe plunger, the

turn movement.

position the trigger may ing with the shoulder I 011 the shank I, Whilethe rear end of said lever extends on the opposite side of the fulcrumto a point for engagement with the trigger Q. There is also provided aspring P which at one end engages a notch in the lever P and at itsopposite end abuts against the link 0. T e arrangement is such thatwhenever the handle B is drawn backward along the guide C the levers Mand M will be bent downward, and the lever M through the medium of thelink 0 will force the sliding abutmentL forward, compressing the springK and carrying the sear P to a position where the hook P will engagewith the shoulder I of the'shank I. the hook in this abutment L will Thespring P will hold engagement, and thus the be held in fixed relation topring being compressed therebetween. This will permit of a movement ofthe plunger, spring and abutment rearward by the forward movement of thehandle B until the levers M and M are straightened and the rear end ofthe sear lever comes into operative relation to the trigger Q.

During the operation of spring the sear being withdrawn from the triggeris out of the influence of the latter, so that when the hook P engageswith the shoulder I these parts cannot be disengaged until the leversare returned to their normal position. To prevent any prematuredisengagement after the sear has come into proximityto the trigger, thelatter is locked during the whole lever movement and is only released atthe completion of the re- To accomplish this, the trigger Q is providedwith a locking member R which is in the form of a dog pivoted on the,pin H, the free end of said dog being engageable with a notch Q in thetrigger. 3

R is a spring which engages with the dog R to force the same into aposition for engaging with the, notch Q, but when the parts are innormal position, the rearwardlyprojecting end P, of the sear lever Pbears against the dog R and forces it rearward against the tension ofthe spring R, so as to disengage from the notch Q. In this be pulled,and arm P upward, of the lever and from the shoulder shank I and perwhenrocked will force the depressing the forward end disengaging the hook PI which will release the mit the forward actuation of the plunger by thetension of the spring. A cam portion Q? on the trigger serves to guidethe dog R intoengagement. with the notch Q, and also to force the dogout of the path when the trigger is pulled.

compressing the To cheapen the cost of manufacture, most of the parts,including the trigger and its locking dog R, are formed up from sheetmetal stampings, which are inexpensive to manufacture and are of lessweight than if made from solid metal.
